Petrol particulate filter

[shewdz]

Avid reader of these threads and been both unlucky to have the PPF light come on several times, but also found it relatively easy to clear using the high revs method.

Bit of a new one today though. Car went in for a service and MOT. I requested the PPF related software update i had read about on this forum. When i went to pick the car up, they told me i would have to bring it back to them in a few days. The software update has caused the engine light to come on (which they stated was normal) and to fix it then need to request a "wire" to make the engine light go away. Sounds like they are making it up as they go along. Anyone else had similar?

Thank you to whoever posted the link to the picture I have attached. I have a 2022 Tuscan 1.6 and have had the petrol particulate light illuminating every few months. Paid for 2 regens and then my husband managed to clear the light. The light came on this week and I followed the instructions on the attachment and managed to clear it on a motorway within 5mins. At least I know I can do it myself now and it won’t bother me if it comes on again. Not being sexist but if I am a woman and can do this anyone can

Welcome to the forum, ‘VBuckley’.

The procedure for extinguishing the PPF warning lamp is pretty straightforward but modifying one’s driving habits can help enormously in preventing frequent repetitions of the problem. Consider the overrun part of the cure and try to incorporate that into the daily drive, rather than, as many do, drive at the maximum speed possible and leave braking until the very last moment before negotiating a corner, bend or roundabout for example.

These Tucsons are not sports cars and reward being driven conservatively, rather than ‘pedal-to-the-metal’. There is sufficient oomph available for when it’s required though.

Unless I missed it, you haven’t mentioned which TUCSON model you drive but the ones badly affected by PPF blockages seem to be the MHEV and the regular petrol-only models. Although these cars are designed to be able to run on E10, there is a body of opinion which suggests E5 petrol seems to go some way towards avoiding PPF problems.

At the risk of tempting fate my own car which is the regular petrol engine is mostly used around town, barely gets above 20mph usually, ,is run on Costco's E5 and has had no PPF issues to date . Having used E10 once when I first bought the car and regretted it, I personally now wouldn't use anything other than E5 despite the premium price .

I’m delighted to hear your experience with the non-hybrid car, ‘r0n’. Regardless of the fact that Hyundai & KIA sell these cars with the attraction of owners being able to run them on the cheaper grade of petrol on sale in the UK, I’m afraid that I don’t buy into their advice about the appropriate fuel.

My own experience, first with Hyundai, then with KIA and again with Hyundai, is that all of those cars ran more sweetly, in the case of the first two, on diesel, and on my HEV Tucson, petrol, both fuels being of the premium variety. Having discovered long ago that I could gain the benefits of premium fuel far more cheaply by substituting an additive to the cheaper fuel, rather than than pay the price of premium, particularly in the case of an Optima SW which took, on one occasion, 72 litres!

When weighed up against the aggravation of having to perform regeneration, perhaps multiple times, due to a gummed-up PPF or DPF, I think the additional cost of premium fuel is a price worth paying! I’m sure that if Hyundai/KIA had marketed these cars as requiring premium fuels, we would never have heard of so many complaints about an illuminated DPF/PPF warning lamp.

Yes, and they wouldn't sell as many cars.

Hi there

Just joined so go easy on me!

The ppf warning came on for me today. I have mild hybrid n line 21 plate, automatic, 50m miles.

Not sure if I have dual clutch transmission. I can switch to manual gear.

Had the car 6 months and recent experiences with local dealer have been terrible so want to avoid thing to take it to them.

Apologies for my ignorance, I have read about the regen. Do I have to put it in manual and 3rd gear and keep it in third gear whilst doing the continued acceleration between 2500-4000 or can I have it in any higher gear?

How long do I do this for in terms of minutes?

Cheers

Apologies, that meant to read as 50k miles

You must know, surely, whether it is DCT or the later 6-speed auto with paddles. I’m guessing DCT?

Regardless, the methodology is the same.

Get the engine up to normal operating temperature on a good A-road or motorway and manually select a gear that allows you to easily keep the rpm up close to 4000, without breaking speed limits or being a nuisance to other traffic. At that point, lift off the throttle and count 5-seconds.

Then increase rpm to 4000 again and once there, release the throttle again and do the 5-second count before repeating that manoeuvre as required until the warning lamp is extinguished. It probably won’t take too long but if you fail to achieve success after 20 to 30 minutes, perhaps you need to visit your KIA dealership.

When you eventually rid yourself of that problem, if you have been in the habit of using E10 petrol, I suggest you pay the little bit more and use E5 as there is some anecdotal evidence that suggests the problem occurs far less frequently on the more expensive fuel.

@indalo1

Thanks for your reply. Sorry, I’m not very car savvy so really don’t know if it’s dct or not and don’t know what to look for to determine this.

The car is automatic and has P/R/N/D and has sport mode but no paddles

I can put the car into manual driving mode

I have taken the car for a drive for about 20 mins on the motorway and tried the rev procedure but the light is still on I was in auto driving mode and had enabled sport mode.

Do I need to switch to be permanently in manual rather than auto and keep it in a gear higher than 3 and try again?

Thanks
